The Overview

The supreme Super Audio CD player reigning over all other single chassis models

The Grandioso series is the supreme range of Esoteric products. The Grandioso K1 takes its place at the pinnacle of this range as an all-in-one Super Audio CD player comprised of only the very best in luxurious materials expected of a Flagship model. It adopts a high precision VRDS-NEO VMK-3.5-20S transport mechanism and newly designed premium D/A converters with separate left and right power sources for each of its eight differential circuits. It also includes the AK4497, which is the highest performance DAC in the history of AKM*. Esoteric has also developed “ES-LINK Analog”, an original high quality current transmission method for connecting with the Grandioso F1 Integrated Amplifier. Furthermore, every last corner of its electronic circuits has been refined, such as its 35-bit D/A processing algorithm, a HCLD buffer amplifier including 125,000 μF super capacitors, and a high-precision clock. To put it simply, the Grandioso K1 opens up a new horizon for digital players
